Smashed Performance 21301 Coolant Black Off Plate

Put the Smashed Performance Coolant Plate in your GM 6.6L Duramax to permanently eliminate coolant leaks from the rear housing on your Duramax engine. The factory cover uses a gasket and over time the plate can warp, and the gaskets can corrode causing coolant leaks. The Plate is made from CNC-machined billet aluminum and features a built-in o-ring seal for a leak-free installation. Each coolant plate comes with a black anodized finish and is ready to install re-using your factory hardware.

FEATURES:

• Built-In O-Ring Seal
• Black Anodized Finish
• Billet Aluminum Construction
• Eliminate Rear Housing Coolant Leaks
